I had a client that we manage the network for, and they had a need to use Gradience HR software which needs to acces files that are UAC protected, so only admins could use the program. Vista has a way to bypass UAC for specific programs so any user can now run that program; there is no need for a third party tool. Here is a little how to article on it: http://dailyapps.net/2008/01/hack-attack-disable-uac-for-certain-applications-in-vista/[^]
